I had to replace the swingarm bushings on my quad and since I had to remove the clutches to do this I though about replacing the springs. After reading on here i've pretty much decided to go with the EPI pink primary but i'm still not real sure if I need to replace the secondary spring. The atv is completely stock with no upgrades so do I need to replace the secondary and if so which spring should I use.

 

you can run the pink spring with the stock secondary.I change the secondary for better backshift.
